An important the air-in he vapor drawn into the manifold and into the cylind into the. top of the other end being}; connected above the carburetor 3 valve 14 of any aphich will permit ards the manit in a reverse uel-level maintained in the such as to cover the open take pipe 12 and imatc contactof the air secured since drawn down latter within said pipe and it by the suction created by thus formed is such a. bulk and in such to be readily comhat the back pressure from the t to discharge the liquid k 6 through the ipe 12 employed, t is also -fire communicating with feature in my invention is m eas es the provision of the receiver within high as or above the fuel level in the tank 6,

the host will not he deflected. If the float were subjected to the vigorous bubbling of the fuel it would not properly function and the fuel level could not be controlled.

Gt course the receivenwalls may be carried es high as desired in order to accomplish the desired end.

The rich fuel-mixture possible due to awing the air through the bulk of liquid ruehpermits exceedingly easy starting of motor end as fuel is always maintainedtank 6 from the main source in the his althe continuous action is possible. in practice, the carbunetcr and my invent-ion operate in conjunction, the said csrhuretor being cut down? to a mixture which with the device will give the proper tiring charge, the rich mixture inducted into the manifold supplying the fuel for heavy duty or when the throttle in the csrhuretor is opened to speed up the engine.

I desire to state that the arrangement of the float and in fact all of the parts described herein may be varied at will to suit the desire and sim of the invention since it is not my purpose to confine myself to the specified structure shown.

In addition to the easy starting of the motor, more mileage is realized due to better carbureted fuel mixture, and therefore the motor can be throttled down, a cooler motor results with less use of lubricating oil, and less carbon is formed which means fewer rspsirs and valve grinding.

1. The combination with the intake manifold of an internal combustion engine and a fuel tank for supplying fuel to the carburetor of the engine, of a second tank, a pipe connectin the first named fuel tank with the said car uretor, a branch pipe connecting said pipe with the said second tank, a valve to control the flow of fuel through said branch pipe, a float in said second tank in control of the valve for maintaining a substantially fixed level of thefucl, a compartment in said second tank separate from that having the float but communicating therewith, a pipe depending at one end into the fuel of said compartment and extending into the atmosphere at the other end, and a conduit connecting the said second gap: above the fuel with the intake manii 2. The combination with the intake manifold of an internalcombustion engine and a fuel tank for supplying. fuel to said engins, of a second tank, a fuel pipe connecting the two tanks, a valve in control of the outlet end of the pipe withinjthe said sec- 0nd tank, a float in said second tank controlling the valve, a perforate receiver fixed within the second tank with its top above the level. of fuel therein, a pipe depending at one end into the fuel in'said receiver and extending at its other end-outside the sec ond tank, and a conduit connected at its ends into the said second tank above the fuel level and into the engine manifold.
